Algae-derived Biomolecules; A Versatile Resource and Sustainable Solutions for India's Future

Over the past decade, algae have emerged as pivotal organisms, increasingly acknowledged for their profound ecological contributions and cutting-edge technological applications, particularly in the development of eco-friendly biomolecules. India's tropical climate and abundant sunlight create ideal conditions for large-scale algae cultivation, with oceans rich in microalgae, diatoms, and dinoflagellates. Of the 30,000 to 40,000 species, only a few are commercially utilized, but more can be explored for environmental, energy, and food security benefits. This review investigates algae-derived natural, carbon neutral biomolecules production and highlighting its scope and challenged in India It also outlines how algae can drive sustainability across sectors such as bio plastics, biofuels, food, cosmetics, and pharmaceuticals, along with emerging trends in the fashion industry like bio beads and bio leather. By lowering costs and reducing carbon emissions in algal biorefineries, these strategies contribute to a sustainable future. However, obstacles such as the energy-intensive production process and the need for optimized biorefinery pathways impede large-scale commercialization. Moreover, India's algae products market faces challenges, including low consumer awareness, difficulties in ensuring sustainable sourcing, and strict regulatory standards. Competition from conventional products, coupled with the need for continuous innovation to improve taste and versatility, further complicates market expansion.
